Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
ANSWER
C. 38.83 miles per hour.
EXPLANATION
It was given that, the fuel economy of a car, measured in miles per gallon, is modeled by the function
We rewrite the function in the vertex form by completing the square.
Or
The vertex of this function is
Hence the maximum fuel economy is 25.57 gallons and this occurred at an average speed of 38.83.
The correct answer is C
